Abstract

A visibility transmissometer, for use in measuring visibility in air at airports. The visibility transmissometer has a light transmitter unit 11 and a light receiver unit 13. The light transmitter unit 11 is arranged to transmit light via a light pathway (indicated as 15) to the light receiver unit 13. The light transmitter unit 11 and light receiver unit 13 are each mounted on a pole 17 above the ground 19, located 75 metres apart from each other. The light transmitter unit 11 and light receiver unit 13 are connected by a subterranean communications link 21 (which also includes power supply necessary for operation). A further subterranean communications link and power feed 23 connects the light receiver unit 13 to monitoring equipment which may be located in the control tower at the airport. The light transmitter unit 11 and light receiver unit 13 have a mirror in the optical pathway which can be controlled to align the light beam between the light transmitter unit 11 and light receiver unit 13, by a microprocessor incorporated in the visibility transmissometer. <IMAGE>
